Roll Crusher

6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.

Crushing in Mineral Processing

The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.
